What is the question? The question is "If the sun is spiraling around in some Birkeland current filament (the local interstellar cloud), where is the other filament? You can't just have one filament!" [link to en.wikipedia.org]

So Proxima Centauri, the closest star to the sun, is not in the Local Interstellar Cloud? It's in a cloud right next to ours, and it's cloud is "interacting" with our cloud.Since sometimes it's easier to step back and look at the bigger picture: [link to en.wikipedia.org] Now superimpose the picture from the first link.

Would you consider that the “filament”, perhaps the primary one, for our Sun exist at the ‘interface’ between these “clouds” and thus the reason for the way the Sun is depicted as being offset from center in comparison to the two? All of the references previewed thus far suggest that we are simply moving through them, or that they are simply moving past us. [link to www.thunderbolts.info]

Compare the diagram in section 6.8 here: [link to www.thunderbolts.info] with the picture in: [link to en.wikipedia.org] The local cloud and G cloud are a twisted pair. The sun is near the center and traveling nearly axially. The average particle in the Local cloud is more distant from the central axis, and so the cloud has a more azimuthal component.This is why we don't see are sun moving with the local cloud,but instead see them moving at nearly right angles.

[link to en.wikipedia.org] Or again in this picture, the sun moving nearly down the center of this spiral (which appears to be well defined at the tip of the sun's directional arrow), and the local cloud spiraling more AROUND that axis
